[Superficial stomach cancers: surgical experience and study of prognostic factors in 102 patients]

The aim of this retrospective study was to analyze the characteristics, treatment and prognosis of early gastric carcinoma in a series of 102 patients.

Between 1973 and 1994, 102 patients (68 males, 34 females) with a mean age of 65 years, were operated on for an early gastric carcinoma. Mean follow-up was 7 years. Survival was calculated using the Kaplan-Meier method. Prognosis was determined with univariate and multivariate analysis according to Cox model.

The carcinoma was limited to the mucosa in 57 patients (56%) and extended to the submucosa in 45 (44%). There was a lymph node invasion in 17 patients (16.5%). The postoperative mortality rate was 5.8% (n = 6). Secondary deaths occurred in relation with the gastric cancer in 10.4% (n = 10). The 5- and 10-year actuarial crude survival rates were 84% and 68.6%, respectively. Univariate analysis of prognosis factors showed a significant survival difference according to the age (P = 0.001), submucosal extension (P = 0.03), lymph node invasion (P = 0.0005) and type of gastric resection performed (P = 0.03). With multivariate analysis of prognostic factors, advanced patient age and lymph node metastases were the only statistically significant independent prognostic factors, advanced patient age and lymph node metastases were the only statistically significant independent prognostic factors (P = 0.0002 and P = 0.002, respectively).

Prognosis of early gastric cancer is usually excellent. Patients with high risk of recurrence may be identified in relation with prognostic factors and mainly with lymph node invasion.
